What we observed
On May 17, 2026 at 23:29–23:42 UTC our RTT oracle detected a two-wave MEV stress event on Base.
Timeline:
23:29:43 UTC — Base P99 RTT: 52ms → 739ms (14x spike)23:30:10 UTC — Revert ratio: 0.19 → 0.5623:39:35 UTC — Peak: 61.36% of all Base transactions reverted23:41:52 UTC — Full sequencer stall (P99 = 5000ms timeout)
RTT spike preceded revert wave by 27 seconds.
Why it matters for Gearbox
Gearbox credit accounts execute leveraged strategies across DeFi. During a 61% revert event, liquidations of unhealthy accounts fail repeatedly — increasing bad debt risk. A sequencer health gate enables liquidation bots to pause during stall and retry efficiently.
What we built
Phoenix Zero — 2-second RTT oracle across Base, Arbitrum, Optimism, ZKSync.
